Kaolin Clay Manufacturers in India
Expolica Ceramics extracts premium kaolin from five dedicated mines, delivering high-purity china clay through advanced processing facilities. Our commitment to quality makes us reliable china clay manufacturers in India for ceramic industries nationwide.
- Strategic Mine Locations:Our five mines are strategically positioned in mineral-rich zones known for high-grade kaolin deposits. Geological surveys guide our extraction process, targeting layers with minimal iron content and optimal kaolinite concentration.
- Multi-Stage Purification Process: We employ crushing, grinding, magnetic separation, and centrifugal classification to remove impurities. Each processing stage is monitored to achieve consistent particle size distribution and brightness levels.
- Specialized Grades: As experienced kaolin china clay manufacturers, we produce multiple grades: calcined kaolin for enhanced whiteness, hydrous kaolin for plasticity, and ultra-fine grades for porcelain.
- Technical Support : When manufacturers face issues like cracking, warping, or color inconsistencies, we analyze their clay bodies and recommend kaolin grade modifications.
- Year-Round Supply: Monsoon disruptions affect many Indian clay suppliers, but our multi-mine operations and strategic stockpiling maintain continuous supply. We maintain 90-day reserves of processed kaolin in climate-controlled warehouses.
- Compliance with International Standards: Our kaolin meets specifications outlined by ISO standards and major ceramic body manufacturers globally. Regular third-party testing validates our quality claims for parameters like plasticity index, shrinkage rates, and fired color values.
